Since CBN is typically produced via degradation it is typically not found in high amounts in cannabis unless the bud is not stored in an airtight container or if it has been sitting dormant for a very long time.
CBN is probably known the most for its sedative effects. According to Steep Hill Labs, "The consumption of 2.5mg to 5mg of CBN has the same level of sedation as a mild pharmaceutical sedative, with a relaxed body sensation similar to 5mg to 10mg of diazepam." Because of that, CBN is often described as having weak psychoactive effects. Here are some of its other possible medicinal uses.
-appetite stimulant. Study 1.
-may help with intraoccular pressure
-Nabilone, a well-known pharmceutical derivative of CBN, traded under the name Cesamet in many counties including the U.K., has been extensively studied and is currently available in prescription as an antiemetic and treatment for neuropathic pain.
Possible Therapeutic Effects
NOTE: Categorized as a "Minor" cannabinoid in cannabis.
Unlike most cannabinoids, Cannabinol (CBN) rarely results from the decarboxylation of its acid form - Cannabinolic Acid (CBNa). Instead, most of the CBN found in cannabis is due to the degradation of THC, whereby the THC has oxidized to CBN.
During this oxidation process, the unstable THC molecule, which has the chemical formula C21 H30 O2, loses four hydrogen atoms (which give the THC molecule the tetrahydro- prefix) to convert to CBN. As shown in the graphic below, this process is facilitated by heat, light and air, and does not require the action of an enzyme.
